Referring to the drawings by characters front and rear walls of theheating compartof reference l0 designates the body of the ment areprovided with a vertical portion structure which is preferably built upfrom 37 and with an inclined portion 38 to probrick having an exteriormetallic covering vide the upper part of the compartment 12 11. The bodyis provided adjacent its of gradually increasing areas toward itsuplower portion with a heating compartment per wall. The heatingcompartment 12. 12 and a plurality of superposed oven units the ovenunits 13, 14 and 15 and the flue or 13, 14 and 15. A sinuous conduit orheat conduit 16 are preferably lined with fire conveying flue 16 hascommunication at its brick 39 or a similar substance of this charlowerend as at 17 with the heating compartacter.

Theextreme inner free extremities of the burner pipes are preferablysupported by the metallic strap 43 which extends through the compartment12 from front to rear.

In use and operation of the oven, when the burner islighted, theproducts of combustion in vthe heating compartment will travel therefrominto the conduit or flue 16 embracing the several oven units 13 on threesides to heat the same. It, of course, follows that the lowermost ovenunit being disposed closest to the heating chamber will be heated to ahigher degree of heat than the oven unit 14, and the oven unit 14 to ahigher degree of heat than the oven unit 15, thereby providing an ovenhaving various compartments with relatively different degrees of heatfurnished by a common heating unit in which the heat is .of a constantdegree. The baker is thus afforded three or more compartments or ovenunits of various degrees of heat by means of which baked articlesrequiring difierent degrees of heat may be simultaneously operated uponby a common heating unit.

Having thus described my invention, what I claim is: 4 V

1. In a bakers oven of the character described, a heating chamber havingupwardly vand outwardly inclined walls, a plurality of burners in thechamber, and a deflector plat in the chamber above the burners andhaving upwardly and outwardly inclined edges corresponding to theinclination of the inclined walls of the heating chamber and providedwith feet resting upon the inclined walls of the said heating chamber.

2. A.bakers oven. comprising a body including front, rear, side, top andbottom walls, a plurality of superposed horizontal walls definingindividual ovens each having a doorway communicatin therewith throughthe front wall of the ody, and a subterposed heating chamber havin adoorway through one of the side wal s of the body, a heating conduithaving communication with the heating chamber at one side thereof andextending alternately through the superposed horizontal partitions andthe opposite side walls of the body, a warming cabinet at on side of theoven, and a pipe connecting the upper end of the heating conduit withthe said cabinet.

3. A bakers oven comprising a body including front, rear, side, top andbottom walls, a plurality of su rposed horizontal walls definingindividua ovens each havin a doorway communicating therewith throug 1the front wall of the body and a subterposed heating chamber havingadoorway through one of the side walls of the body, a heating conduithaving communication with the heating chamber at one side thereof andextending alternately through the superposed horizontal partitions andthe, opposite side walls of the body, the said subterposed heatingchamiber having the upper portion of its front and rear walls inclinedoutwardly, a plurality of burners in the heating chamber, and adeflector plate above the burners and having its front and rear edgesinclined outwardly to correspond to the inclination of the upper portionof the front walls of the heating chamber and provided with dependingfeet resting on the inclined wall of the heating chamber, as and for thepurpose set forth.
